Rashi (Sanskrit for zodiac sign) is the foundational sign reference in Vedic astrology. Each rashi is a 30-degree slice of the sidereal zodiac, totalling 12 signs - Mesha (Aries) through Meena (Pisces). Three rashi-derived references matter most for everyday Vedic readings:
To compute Janma Rashi, the tool finds the Moon’s tropical ecliptic longitude at your birth moment using Meeus lunar theory, then subtracts the Lahiri ayanamsa (~24 degrees in 2026) to get the sidereal longitude. The 30-degree segment of the sidereal zodiac in which that longitude falls is your Janma Rashi.
Lagna Rashi (Ascendant) requires the eastern-horizon calculation - which sign was on the local eastern horizon at birth. This depends on your birthplace latitude and longitude and your exact birth time. Lagna changes roughly every two hours, so birth-time uncertainty of even a few minutes can flip Lagna near a sign boundary.

Your rashi is a 30-degree Moon sign (12 in all); your birth star (nakshatra) is a finer 13 degree 20 minute lunar mansion (27 in all), each divided into four padas. One rashi spans about 2.25 nakshatras, so your rashi does not pin your nakshatra - they are related but separate readings.
This page focuses on your Moon sign and Ascendant. For your nakshatra, pada, the traditional naming syllable (akshara), and your star’s name in Malayalam, Tamil, and Telugu, use the Birth Star Calculator.
The traditional approach uses a Panchang (Hindu almanac) cross-referenced against your birth date and time. Look up the Moon’s nakshatra at your birth moment in the Panchang, then use the rashi-of-nakshatra mapping (each rashi spans ~2.25 nakshatras). For example, Bharani nakshatra falls in Mesha (Aries), Krittika nakshatra straddles the Mesha-Vrishabha boundary, and so on.
The Moon’s exact longitude varies by year, so this only works if you have a Panchang for your specific birth year. Most modern users prefer a calculator like this one for accuracy.
Rashi is the Sanskrit term for a zodiac sign in Vedic astrology. Janma Rashi (also called Chandra Rashi) is the sign the Moon occupied at your moment of birth. Lagna Rashi (also called Ascendant) is the sign rising on the eastern horizon at your birth moment. Both are computed using the sidereal Lahiri ayanamsa, the convention adopted by the Indian Government's Rashtriya Panchang.
Provide your date of birth, time of birth, and place of birth. The tool computes the Moon's sidereal longitude at that exact moment using Meeus lunar theory, subtracts Lahiri ayanamsa to get the sidereal position, and reports the corresponding zodiac sign. Janma Rashi changes every ~2.25 days, so birth time matters most on Moon-transition days; Lagna Rashi changes every ~2 hours so birth time is essential for accurate Ascendant.
Janma Rashi is the Moon's sidereal zodiac sign at birth - it represents emotional nature and mind in Vedic tradition. Lagna Rashi is the rising sign at birth - it represents personality and outward expression. Janma Rashi is used for Panchang, muhurta, and Dasha calculations; Lagna Rashi is used for chart house assignments and personality predictions. Both come from the same birth chart.
No. Indian Rashi uses the sidereal Lahiri ayanamsa with the Moon's position; Western zodiac uses the tropical zodiac with the Sun's position. The two systems differ by approximately 24 degrees as of 2026 (the ayanamsa) - so most people's Western Sun sign and their Indian Janma Rashi are different. If your Western Sun sign is Aries, your Indian Janma Rashi could easily be Pisces or even Aquarius depending on your exact birth date.
Use the 'I don't know my birth time' toggle. The tool will use 12:00 noon local time at your birthplace as the default. Janma Rashi (Moon sign) is usually still correct because the Moon stays in one sign for ~2.25 days; the tool also explicitly checks whether the Moon transitioned to a new sign during your birth date and, if so, shows BOTH possible Rashis with the local transition time. Lagna Rashi cannot be computed without an accurate birth time and is shown as unknown.
Rashi is a 30-degree zodiac sign (12 total). Nakshatra is a 13 degree 20 minute lunar mansion (27 total). The Moon traverses one Rashi in ~2.25 days and one Nakshatra in ~24 hours, so one Rashi spans about 2.25 nakshatras. This Rashi Calculator returns your Moon sign and Ascendant; for your nakshatra (birth star), pada, and the traditional naming syllable, use the dedicated Birth Star Calculator.
No. Your Janma Rashi is fixed by the position of the Moon at your birth - it cannot change over your lifetime. What can change is transiting Saturn or Jupiter through your Janma Rashi (such as Sade Sati when Saturn is in or adjacent to your Moon sign). Your Lagna Rashi is similarly fixed by your birth moment.
In sidereal Vedic order: Mesha (Aries), Vrishabha (Taurus), Mithuna (Gemini), Karka (Cancer), Simha (Leo), Kanya (Virgo), Tula (Libra), Vrishchika (Scorpio), Dhanu (Sagittarius), Makara (Capricorn), Kumbha (Aquarius), Meena (Pisces). The English equivalents are the same constellation names used in Western astrology, but the Vedic system uses the sidereal zodiac so the dates differ.
The underlying Moon position is computed via the Meeus lunar theory with Lahiri ayanamsa - typical precision is around 0.3 degrees vs Swiss Ephemeris. The Moon moves ~13 degrees per day, so this position bound translates to roughly 33 minutes of birth-time uncertainty for sign assignment. Far from sign boundaries, the result is unambiguous. Within 0.3 degrees of a sign boundary, the tool surfaces a dual-rashi output with the local transition time so you can decide based on your actual birth time precision.
None. Rashis are not 'good' or 'bad' in classical Vedic astrology - they are reference frames for chart computation. Specific outcomes depend on planetary positions, aspects, dashas, and transits within the chart. Avoid sources that claim particular Rashis are inherently lucky or unlucky; that framing is not in the classical texts and is a modern reduction.
